I loved it. What was unusual about this episode was that they relied more on visual gags than on dialogue. In fact, this was perhaps the most physical comedy the show's ever done in one episode and I thought that the cast did it perfectly. I think that the ending with Phil, Claire and Haley was a nice, low key kind of an ending, but it didn't have that usual "grand statement about life and family" voice over while we cut to all of the characters, so it didn't feel as wrapped up as it usually does.
On a side note, I thought that this episode was ALL about Julie Bowen. Not only was she 100% game for all the physicality she had to do (I think she's secretly the show's best physical comedian), but she played Claire's descent into a breakdown beautifully. Her scene with Phil talking about how Alex is leaving and how she lost Haley brought a tear to my eye (the way she choked on tears when said that Haley "hates me" was subtle and incredible) and almost made me reach for my phone to call my own mom. Now THAT'S powerful stuff!
